The Secretary of State may by a further direction revoke a direction under paragraph 3 at any time before the determination of the appeal.

Such a further direction shall state the reasons for which it is given and shall be served on the person, if any, previously appointed to determine the appeal, the appellant, the local planning authority and any person who has made representations relating to the subject matter of the appeal which the authority are required to take into account under F1any provision of a development order made by virtue of section 71(2)(a).

Where such a further direction has been given, the provisions of this Schedule relevant to the appeal shall apply, subject to sub-paragraph (4), as if no direction under paragraph 3 had been given.

Anything done by or on behalf of the Secretary of State in connection with the appeal which might have been done by the appointed person (including any arrangements made for the holding of a hearing or local inquiry) shall, unless that person directs otherwise, be treated as having been done by him.
